Rheem-Ruud AP13155-2 Damper Assembly

The Rheem-Ruud AP13155-2 Damper Assembly is a critical 9-inch combustion air control component designed for high-efficiency commercial water heaters and power-vented systems. As a veteran-grade HVAC replacement part, this vent hood damper assembly ensures precise management of exhaust gases by opening during the firing cycle to facilitate safe venting and closing during standby to prevent significant heat loss and backdrafts. Built to rigorous OEM technical specifications, the AP13155-2 provides a direct replacement for AP13155-1, offering seamless backward compatibility for existing Rheem G37-200-1 series and similar high-output heating equipment. This heavy-duty assembly is engineered to withstand the thermal stresses of 199,000 BTU input systems, maintaining consistent static pressure and optimizing venting efficiency. For contractors performing maintenance or repairs on Rheem-Ruud water heaters, utilizing this genuine factory-authorized part is essential for preserving system integrity and ensuring compliance with manufacturer safety standards.

• Direct Replacement: Engineered as the precise AP13155-2 replacement for AP13155-1, ensuring zero-clearance compatibility with legacy power-vented setups.
• High-Capacity Performance: Optimized for 9-inch vent collars, supporting high-BTU commercial gas water heaters without restricting airflow.
• Energy Retention: The automated damper assembly seals the flue during off-cycles to minimize standby energy loss and improve thermal efficiency.
• Robust Construction: Fabricated with industrial-grade materials to resist corrosion and handle high exhaust temperatures common in HVAC/R applications.

Common Questions

Is the AP13155-2 compatible with older AP13155-1 models?
Yes, the Rheem-Ruud AP13155-2 is the manufacturer-designated superceding part for the AP13155-1. It features the same 9-inch collar diameter and mounting footprint for a drop-in installation.

What is the primary function of this damper in a commercial water heater?
This vent hood assembly acts as a motorized gate that allows combustion products to exit the building only when the burner is active, protecting the system from backdrafts and environmental contaminants.

Does this assembly include the necessary wiring for the power vent?
This is the complete damper assembly; however, field technicians should always verify the condition of existing wiring harnesses and end switches to ensure the control board correctly sequences the damper with the blower motor.
